IMPROVEMENT IN UMBRELLA-HANDLES.

Specification forming part of Letters Patent No. 160,603, dated March 9,1875; application filed December 22, 1874.

To all whom it may concern:

Be it known that I, EPHRAIM LAYMAN, of Brooklyn, E. D., in the county ofKings and State of New York, have invented an Iniprovement in Handlesfor Umbrellas, Src., of which the following is a specification:

Difficulty is experienced in making handles for umbrellas, parasols,knives, 8vo., out of bone, because the bone is hollow and notsufiiciently thick to be cut up into pieces of the size necessary forsuch handles. Efforts have been made to unite two or more pieces of bonetogether to form such handles, but they have been liable to variousobjections. The slabs or pieces have been riveted together, but therivets mar the appearance. There have been screws out around the ends ofthese sections, and screw-bands have been placed thereon, but metal isobjectionable in appearance, and bone is liable to crack and break; andmetal rings have been let in tlush with the surfaces of the sections atthe ends.

My invention relates to securing these sections by an internal screwtoward the middle or one end of the sections, and then holding thesections from being turned upon each other by a socket at one end, andwhere this socket is to be out of sight it is formed of a short metalcylinder entering circular grooves in the opposite ends, that arebrought together, so that one length is secured to the next by the samemeans that are employed to hold the sections one to the other. By thismeans the most beautiful and strong handles can be made cheaply. 4

In the drawing, Figure l is a longitudinal section, and Fig. 2 is across-section at the line :v x, of the improved handle.

The sections a b are screwed together by the internal concealed screw c,that is preferably of bone, and is inserted into holes inthe opposingfaces of the sections, said holes having threads cut in them, and thesections are screwed together by rotating one or the other around thescrew c until the surfaces of a and b are made to bear firmly upon eachother. The screw c may be in the middle or toward one end of the handle,and a socket at the end prevents the sections a b being turned upon eachother. rThis socket may be of bone, and of suflicient size to receivethe ends of the sections a b,- but I prefer to make the socket of theshort metal cylinder d, that is introducedinto an annular groove formedat the end of each section, and these annular grooves are of a depthequal to about half the length of the metal cylinder, so that thecylinder 'd enters both grooves in the adjoining lengths, and to drawthe parts together the screw e is inserted into the holes provided forit.

These means for uniting the separate sections of bone are very strong,reliable, durable, and cheap, and the handle can be carved, engraved, orinished in any desired manner, and the connecting devices do not extendto the surface.

This mode of constructing handles is especially adapted to bone; but itmay be used with ivory or other material that has to be united insections, and these handles may be gtglapted to parasols, umbrellas,knives, forks,

I claim as my inventionl. The handle made of the sections a b, united bythe internal concealed screw o, and provided with a socket at one end,as set forth.

2. A handle having the short cylinder l in serted at one end into acircular groove in the sections a b, and at the other end entering asimilar groove in the next length, in combination with the connectingscrew e, as set forth.

Signed by me this 17th day of December, A. D. 1874.
